Many Oracle Linux systems come configured with liberal administrative privileges for non-root users. These privileges should not be made available to users who log in using a Sun Ray Client.

To limit administrative access, do the following:

For example, a line that reads:

<console>=tty[0-9][0-9]* vc/[0-9][0-9]* :[0-9]?[0-9] :[0-9]

should instead read:

<console>=tty[0-9][0-9]* vc/[0-9][0-9]*

And a line such as the following example should be removed:

<xconsole>=:[0-9]?[0-9] :[0-9]
